Embodiment Construction

[0037] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0038] The wiring density in the wiring area of ​​the display is relatively high, which affects the effective contact area between the insulating film layers on the upper and lower sides of the wiring line, and the phenomenon of film layer peeling is prone to occur, such as figure 1 and figure 2 As shown, in the display substrate of the related art, the source-drain metal wiring 2 is arranged on the interlayer insulating layer 1, and the side of the source-drain metal wiring 2 away from the interlayer insulating layer 1 is provided with a planar layer 3. Since the wiring The wiring density of source and drain metal wiring 2 in the area is relatively high, resulting in a small effective contact area between the interlayer insulating la...

Abstract

The invention provides a display substrate, a manufacturing method of the display substrate and a display device, and belongs to the technical field of display. The display substrate comprises a firstinsulating layer located on a substrate, a conductive wire located on one side, far away from the substrate, of the first insulating layer, and a second insulating layer located on one side, far awayfrom the substrate, of the conducting wire, wherein at least a part of the area on the surface of one side, facing the second insulating layer, of the first insulating layer is uneven. According to the technical scheme, the reliability of the display device can be improved.

Description
